The Fourth Dimension is a 30-page interactive book that explains a single mathematical idea in language that anyone can understand. Instead of static images or canned videos, this app employs a unique 3D touch interface that lets you literally grasp the concept of the fourth dimension with your own hands.
“Not only can you blow your own mind over and over again, you can also enjoy watching your friends’ minds being blown in front of you.” — Cult of Mac
“One of the coolest apps I've ever used... The Fourth Dimension is to boring learning apps what Carl Sagan's Cosmos was to staid science documentaries.” — BuzzFeed
“The app is very cool, and it's unlike pretty much anything we've seen in the App Store.” — The Verge
“This is one of my most favorite iOS apps ever.” — George Musser, contributing editor for Scientific American and author of The Complete Idiot's Guide to String Theory
(App Store user reviews follow.)
“Blew my mind. I generally don't use 'learning' apps as they're mostly gimmicks. This one, though, truly made me think. I hope this developer comes out with more outstanding apps such as this one. Bravo!” — Iceitic
“Astounding. That some people care passionately enough about tesseracts to go create a fantastic app for others to understand them is incredible. The app is extremely well designed, wittily written, and executed with love. That alone is worth buying it, besides the fact that I learned what the hell a tesseract was.” — Duncan MacMichael
“Fantastic! This is what someone really smart, and who really knows how to teach well, can do with a tablet. And the authors are funny, too, which is a neat bonus.” — DNY
“Fantastic app. I work at a leading UK university. If only all our material was this well written and presented. Definitely worth buying and then spending a bit of time with over a day or two to get your head around the fourth dimension. Great app!” — JulesFM
“Great job! This app does the best job explaining the 4th dimension. Why learn it in some boring classroom when here you can have an interactive and visual explanation.” — Aco Strklalj
What's New in Version 1.4
Added language selection option.
Beautiful. Necessary. Simple.
This little tutorial gives me hope. Perhaps one day in the distant future, we will have interstellar kindergartens teaching humans how to build and play with impossible 4-dimensional objects.
The next dimension is rightfully hidden from us. It's a place so bizarre and alien to us that we have to talk around it using geometric symbols. A mere glimpse of it is enough to drive physicists to a lifetime of study and mathematicians to fits of ecstatic mathematicing.
I'm just a guy who works in an office and saw this free app and thought it was cool. Now my wife is rolling her eyes at me while she sweeps up by brains off the floor. My brains are still in my head so I don't know how they are also on the floor, but what I do know is this: you owe it to yourself to download this app and give it a go. Do it for your brain cells. Do it for your children. Do it for your country.
PS- Dev team: A VR version might be super fun and could land you in the history Ebooks as one of the catalysts for the 4D revolution.
Every science nerd needs this app. I understood it on the first try even though I'm at an age where I shouldn't even be thinking about the fourth dimension!
This app allows you to visually understand how a four dimensional cube works. I already knew some things, but this app deepened the understanding. Some people may think ,"This app is ok, but the app is not worth the price." But, if you're a total nerd like me, it definitely is!
Blew My Mind
This app does a significant job at explaining the fourth dimension. I had a little understanding of it, then I installed this app and know it completely. The one negative I have is the content:price ratio. There is only about 10-15 minutes worry of content, while the price is $3. Other than the price, I definitely recommend this app.
